Sawtooth Peaks really a series of jagged spires are some of the most easily reached high peaks of the Beartooths but its still at least a 5 mile walk one way. Take the Lulu pass road outside of Cooke city and then after several miles turn left on the Goose Lake Jeep Trail.
This jeep trail is quite rough and you may want to stop and park even if you have a four wheel drive. Continue walking or driving past Round, Star, Astral and finally Goose Lake. The trail is visible up to a pass between Iceberg Mountain and Sawtooth Peak. Its a beautiful area with jagged peaks and alpine lakes and well worth a day or even an overnight.
